State agencies must consider the emissions performance of suppliers when procuring steel, flat glass, and mineral wool insulation for state infrastructure projects.

The state must achieve a 40% reduction in cement emissions by 2035, and net-zero by 2045, relative to 2019 levels.

CARB must also develop a framework for measuring and reducing the embodied carbon of building construction materials, primarily at the materials production stage, and can utilize an embodied carbon trading system as a potential path to achieve the required GHG reductions.

The state has a target to reduce HFC emissions to 40% below 2013 levels by 2030.

The state prohibits certain HFCs in specific stationary refrigeration and air-conditioning end-uses.

From 2011-2020, the annual maximum rate of SF6 emissions was reduced by 1 percent each year. Since 2020, the maximum SF6 emissions rate cannot exceed 1 percent for any owners of SF6-insulated switchgear.

Starting in 2025, utilities are restricted from purchasing SF6 equipment after certain dates, require new emissions limits, set reporting requirements, and maintain gas-insulated equipment inventories.

The Department of Conservation’s Geologic Energy Management (CalGEM) Division prohibits issuing new permits to conduct well stimulation treatments, including fracking, for oil and gas wells.

Methane emissions must be reduced 40% below 2013 levels by 2030.

Food waste target – 50% reduction by 2020 and 75% by 2025, relative to 2014 levels.

Food waste ban – The state requires commercial generators of organic waste to either compost or anaerobically digest organic waste.

Municipal solid waste landfills must reduce methane and other air pollutant emissions through emissions monitoring and through capturing fugitive methane.
